These parameters represent the 10 table values
stored that designate what analog output value
achieves the corresponding cc/min. The value
ranges from 0 to 4095 and corresponds to an
analog output of 0-10 VDC.

These parameters represent the values that the
flow controller stores when a new point is stored.

The table shown above is established based on
actual flow rates that the controller has achieved
or based on a calculation if less than 10 points are
stored. For example, if the flow controller learns a
value of 200 and then is taught a value of 20, the
table would range from 20 to 200 in ten equal
increments. As each intermediate point is
requested, the flow controller interpolates the output
value based on a linear curve. When the new set
point is reached, the actual flow rate and analog
out value would replace which ever existing point
is closest. If a new maximum or minimum value is
taught that is outside the current curve, the opposite
end of the table is retained and a new linear curve
is calculated. Due to the operation of the tables, it
is important to understand how the controller learns
a new value to prevent the flow controller from
constantly learning new points and defeating the
benefit of the lookup table. If the flow rate requested
is outside the existing curve, the controller will pick
the point closest to the actual request and will use
PID control to reach the new point. When the flow
becomes stable, the new point is stored and the
table is recalculated.

The Normal Block Transfer read is identified by
the configuration word in the BTR file being equal
to zero. This file is returned immediately following
a Normal BTW instruction.
